anodyne

When your back is killing you from helping your friend move furniture into his new apartment, you need to take an anodyne, a painkiller.

An anodyne doesn’t have to be actual medicine. If the pure joy of helping your friend is soothing enough to make you forget your aching back, that counts as an anodyne too (though perhaps an unlikely one). Anodyne can also be used as an adjective to describe something that relieves pain, or is at least inoffensive. When you’re stressed out or unhappy, try looking at anodyne pictures of kittens. Er, unless you had a bad experience with a cat once.
